Objective To explore the causes and treatment of repeated vulvovaginitis in girlhood in order to improve its prevention and treatment.Methods Fifty-one girls with repeated vulvovaginitis(age≤10 years)admitted to The Second Affiliated Hospital of Sun Yat-sen University from Jan.1990 to Nov.2004 were reviewed retrospectively.Results We found 28 girls(55%)suffering from non-specific vulvovaginitis and 14 ones(27%)suffering from posterior recto-vaginal fistula with in 51 patients.Five girls(10%)were smitten with vulval ulcer and 3 ones(6%)had been were found with vaginal foreign bodies.One girl(2%) was smitten with adhesion of labia minora.The vaginal discharges taken from 21 girls were cultured. Seventeen cases found bacteria.The positive rate of bacteria culture in the 21 cases reached 81%,in which, E.coli accounted for 5 cases(24%),staphylococcus and streptococcus accounted for 3 cases(14%) respectively.Patients suffered from non-specific vulvovaginitis and vulval ulcer accepted external lotion, antibiotic ointment or combining with antibiotics.Patients suffered from posterior recto-vaginal fistula accepted fistulectomy.Three girls who found vaginal foreign bodies took out of foreign bodies by hysteroscopo.Fifty-one girls all were cured after appropriate therapy.Conclusions Vulvovaginitis is the most common gynecologic diagnosis in girlhood.The principal cause of repeated invasion is non-specific vulvovaginitis and the secondly one is posterior recto-vaginal fistula.It need overhaul during the diagnosis.It is very availability to use hysteroscopy and do bacteria culture+antibiotic sensitivity test for repeated pediatric vulvovaginitis.

Objective To compare the accuracy of 64-slice spiral coronary angiography (CTA) and myocardial perfusion imaging (MPI) in the detection of functionally relevant coronary artery disease (CAD). Methods Twenty patients diagnosed as CAD and 11 suspected CAD were studied. Both 64-slice spiral CTA and MPI images were analyzed. For the evaluation of CTA,luminal narrowing ≥50% and ＜50% were visually assessed. Perfusion defects on MPI were detected and allocated to their corresponding coronary vessels.Results Among total 124 coronary vessels, CTA detected stenoses ≥50% in 23 arteries, and 7 showed perfusion defects in the corresponding myocardial areas on MPI. Ten of 101 vessels had stenoses＜50%,and no perfusion defects in the corresponding myocardial areas was found on MPI. There was difference between the degree of coronary artery stenoses and the risk probabilities of myocardial ischemia (χ~2=6.667, P=0.01). No statistical difference was detected between the coronary artery stenoses site and the risk probabilities of myocardial ischemia (χ~2=6.839, P=0.065). The sensitivity, specificity, negative and positive predictive values of 64-slice spiral CTA in detecting perfusion defects on MPI was 41.18%, 85.05%, 90.01% and 30.43%, respectively.Conclusion 64-slice spiral CTA can display important morphologic information of coronary arteries, but with a low positive predictive value. MPI can be used as an important method to evaluate the change of heart function resulted from CAD.

OBJECTIVETo investigate surgical treatment approach of transclavicular and transsternal tumor.

METHODSTwelve cases of neck-root and mediastinum thoracis tumor subjected to cervicothoracic-combined surgical treatment were retrospectively analyzed and summarized.

RESULTSSeven cases of benign tumor survived 1-8 years after surgery. The other 5 patients were malignant tumor. Among 4 cases of metastatic squamous cell carcinoma without definite origin at neck-root site who underwent operation and routine radiotherapy, one case died of orthotopic relapse and armpit metastasis at the 16th months postoperatively; one case was lost of follow-up after surgery; another two cases showed no relapse after follow-up of 50 months and 27 months, respectively. In addition, one case of thyroid papillary carcinoma located at neck-root and mediastinum remained alive for 40 months after operation combined with radiotherapy and chemotherapy.

CONCLUSIONSThe evaluation of twelve cases of transclavicular and transsternal tumor with adoption of cervicothoracic-combined surgical approach improves and develops traditional knowledge of surgical therapy of neck-root tumors.

Objective To explore the effects of modified tubo-uterine implantations performed on women with proximal tubal occlusive infertility after femal sterilization with mucilago phenol.Methods Two hundred and eight infertile women who were admitted to the Second Affiliated Hospital of Sun Yat-sen University between 1986 and 2004 were included.They all accepted modified tubo-uterine implantation after occlusion of fallopian tubes with mucilago phenol.Results It was found that the occlusions were all located in the interstitial portion or isthmic portion of the fallopian tubes.Different degrees of pelvic adhesions were found in 65 cases.Fifty-seven cases were slightly adhesive,seven cases were of moderate degree and one case was severe.One hundred and ninety-nine cases were followed up after operations(95.7%).One hundred and ninety-three women accepted hydrotubation in the following month just after the operation and 185 women were found to be unobstructed(95.8%).One hundred and forty-three women became pregnant, the pregnant rate being 71.9%(143/199).One hundred and twenty-five women had term deliveries (87.4%),three women were in early pregnancy and two in midtrimester pregnancy.Eleven women had spontaneous abortion(7.7%).Two women had tubal pregnancy(1.0%).None of the 199 cases had any signs of endometriosis.Conelusions Modified tubo-uterine implantations are quite effective for proximal tubal occlusive infertility.It may be a favorable method for such kind of tubal occlusions.
